ABSTRACT

Provided are an organic electric element comprising as a phosphorescent host material, a mixture of the compounds of Formula (1) and Formula (2), and an organic electronic device or apparatus thereof for achieving a high luminous efficiency, a low driving voltage, and an improved lifespan.

BACKGROUND Technical Field

The present invention relates to compound for organic electronicelement, organic electronic element using the same, and an electronicdevice thereof.

Background Art

In general, organic light emitting phenomenon refers to a phenomenonthat converts electronic energy into light energy by using an organicmaterial. An organic electronic element using an organic light emittingphenomenon usually has a structure including an anode, a cathode, and anorganic material layer interposed therebetween. Here, in order toincrease the efficiency and stability of the organic electronic element,the organic material layer is often composed of a multi-layeredstructure composed of different materials, and for example, may includea hole injection layer, a hole transport layer, an emitting layer, anelectron transport layer, an electron injection layer and the like.

A material used as an organic material layer in an organic electronicelement may be classified into a light emitting material and a chargetransport material, such as a hole injection material, a hole transportmaterial, an electron transport material, an electron injection materialand the like depending on its function.

In the case of a polycyclic compound containing a heteroatom, thedifference in properties according to the material structure is so largethat it is applied to various layers as a material of an organicelectronic element. In particular, it has characteristics of differentband gaps (HOMO, LUMO), electronical characteristics, chemicalproperties, and physical properties depending on the number of rings,fused positions and the type and arrangement of heteroatoms, thereforeapplication development for layers of various organic electronicelements using the same has been progressed.

As a representative example thereof, in the following Patent Documents 1to 4, the performance of the 5-membered cyclic compound in thepolycyclic compound has been reported depending on the hetero type,arrangement, substituent type, fused position, and the like.

-   [Patent Document 1]: U.S. Pat. No. 5,843,607-   [Patent Document 2]: Japanese Laid-Open Patent Publication No.    1999-162650-   [Patent Document 3]: Korean Published Patent Application No.    2008-0085000-   [Patent Document 4]: US Patent Publication No. 2010-0187977-   [Patent Document 5]: Korean Published Patent Application No.    2011-0018340-   [Patent Document 6]: Korean Published Patent Application No.    2009-0057711    Patent Documents 1 and 2 disclose an embodiment in which the    indolecarbazole core in which the hetero atom in the 5-membered    cyclic compound is composed only of nitrogen (N) is used, and an    aryl group substituted or unsubstituted in N of indolocarbazole is    used. However, in the prior invention 1, there exists only a simple    aryl group substituted or unsubstituted with an alkyl group, an    amino group, an alkoxy group, or the like as a substituent, so that    the effect of the substituents of the polycyclic compounds was very    poor to prove, and only the use as a hole transport material is    described, and the use thereof as a phosphorescent host material is    not described.

Patent Documents 3 and 4 disclose a compound in which pyridine,pyrimidine, triazine or the like containing an aryl group and N,respectively, were substituted for an indolecarbazole core having ahetero atom N in the same 5-membered cyclic compound as in the abovePatent Documents 1 and 2, however only the use examples forphosphorescent green host materials are described, and the performancefor other heterocyclic compounds substituted for indolecarbazole core isnot described.

In Patent Documents 5, Nitrogen (N), oxygen (O), sulfur (S), carbon andthe like are described as heteroatom in the 5-membered cyclic compound,however there are only examples using the same heteroatom in theperformance measurement data, the performance characteristics of a5-membered cyclic compound containing a different heteroatom could notbe confirmed.

Therefore, the patent document does not disclose solutions to low chargecarrier mobility and low oxidation stability of a 5-membered cycliccompound containing same heteroatom.

When the 5-membered cyclic compound molecules are generally laminated,as the adjacent π-electrons increase, they have a strong electronicalinteraction, and this is closely related to the charge carrier mobility,particularly, the same 5-membered cyclic compound of N—N type has anedge-to-face morphology as an order of arrangement of molecules whenmolecules are laminated, otherwise a different 5-membered cycliccompound with different heteroatoms has an antiparallel cofacialπ-stacking structure in which the packing structure of the molecules isopposite to each other, so that the arrangement order of the moleculesbecomes face-to-face morphology. It is reported that the steric effectof the substituent substituted on the asymmetrically arranged heteroatom N as the cause of this laminated structure causes relatively highcarrier mobility and high oxidation stability (Org. Lett. 2008, 10,1199).

In Patent Document 6, an example of using as a fluorescent host materialfor various polycyclic compounds having 7 or more membered cycliccompounds has been reported.

As described above, the fused positions, the number of rings, thearrangement of heteroatoms, and characteristic change by type of thepolycyclic compounds have not yet been sufficiently developed.

Particularly, in a phosphorescent organic electronic element using aphosphorescent dopant material, the LUMO and HOMO levels of the hostmaterial have a great influence on the efficiency and life span of theorganic electronic element, this is because the charge balance controlin the emitting layer, the quenching of the dopant, and the reduction inefficiency and life span due to light emission at the interface of thehole transport layer can be prevented, depending on whether electron andhole injection in the emitting layer can be efficiently controlled.

For fluorescent and phosphorescent host materials, recently we have beenstudying the increase of efficiency and life span of organic electronicelements using TADF (thermal activated delayed fluorescent), exciplex,etc., particularly, and many studies have been carried out to identifythe energy transfer method from the host material to the dopantmaterial.

Although there are various methods for identifying the energy transferin the emitting layer for TADF (thermally activated delayed fluorescent)and exciplex, it can be easily confirmed by the PL lifetime (TRTP)measurement method.

The TRTP (Time Resolved Transient PL) measurement method is a method ofobserving a decay time over time after irradiating the host thin filmwith a pulsed light source, and therefore it is possible to identify theenergy transfer method by observing the energy transfer and the lagtime. The TRTP measurement can distinguish between fluorescence andphosphorescence, an energy transfer method in a mixed host material, anexciplex energy transfer method, and a TADF energy transfer method.

There are various factors affecting the efficiency and life spandepending on the manner in which the energy is transferred from the hostmaterial to the dopant material, and the energy transfer method differsdepending on the material, so that the development of stable andefficient host material for organic electronic element has not yet beensufficiently developed. Therefore, development of new materials iscontinuously required, and especially development of a host material foran emitting layer is urgently required.

Otherwise, the synthesis examples of the present invention representedby Formulas (1) and (2) have been described, but these are all based onthe Buchwald-Hartwig cross coupling reaction, Suzuki cross-couplingreaction, Intramolecular acid-induced cyclization reaction (J. mater.Chem. 1999, 9, 2095.), Pd(II)-catalyzed oxidative cyclization reaction(Org. Lett. 2011, 13, 5504), Grignard reaction, Cyclic Dehydrationreaction and PPh3-mediated reductive cyclization reaction (J. Org. Chem.2005, 70, 5014.), and those skilled in the art will readily understandthat the above reaction proceeds even when, besides the substituentspecified in the specific synthesis example, other substituents (R¹ toR⁵, Ar¹ to Ar⁴, L¹ to L², X¹ to X²) defined in Formula (1) are bonded.

For example, Sub 1+Sub 2→Final Products 1 reaction in Reaction Scheme 1,the synthetic reaction of Sub 2 in Reaction Scheme 2, Sub 3+Sub 4→FinalProducts 2 reaction in Reaction Scheme 3 are all based on theBuchwald-Hartwig cross coupling reaction, and Sub 3-2+Sub 3-3→Sub 3-4reaction in Reaction Scheme 4 is based on the Suzuki cross-couplingreaction, and Sub 3-4→Sub 3 in Reaction Scheme 4 is based on thePPh3-mediated reductive cyclization reaction (J. Org. Chem. 2005, 70,5014.) The above reactions will proceed even if a substituent notspecifically mentioned is bonded.

As can be seen from the results of Table 6, when the organic electricelement material of the present invention represented by Formulas (1)and (2) is mixed and used as a phosphorescent host (Examples 1 to 100),it was confirmed that the driving voltage, efficiency, and life spanwere significantly improved as compared with the element (comparativeexamples 1 to 7) using a single material. More specifically, inComparative Examples 1 to 7, wherein the compounds of the presentinvention represented by Formula (2) and comparative compounds 1 to 4are used alone as a phosphorescent host, Comparative Examples 1 to 3using the compounds (3-6, 3-61, and 3-74) of the present invention hadhigher efficiency and longer life span than Comparative Examples 4 to 7using the comparative compound.

Also, Comparative Example 8 and 9 wherein Comparative Compound 1 and 2or Comparative Compound 3 and 4 were mixed and used as a phosphorescenthost were found to exhibit higher efficiency than Comparative Examples 1to 7 using the single substance. Comparing Comparative Example 8 with 9,Comparative Example 9 using a mixture containing a polycyclic compoundhaving a different heteroatom (N, S) among the 5-membered compounds hadhigher efficiency than Comparative Example 8 mixed a 5-memberedheterocyclic compound having the same nitrogen atom. And it wasconfirmed that Example 1 to 100 using the mixture of the compound ofFormula (1) and (2) as a host exhibited remarkably high efficiency andlong life span than the Comparative Example 1 to 9.

On the basis of the above experimental results, the inventors of thepresent invention have found that, in the case of a mixture of thesubstance of Formulas (1) and (2), they have novel characteristics otherthan those for the respective materials, and have measured the PLlifetime using the substance of Formula (1), the substance of Formula(2), and the mixture of the present invention. As a result, it wasconfirmed that a new PL wavelength was formed when the compounds ofFormulas (1) and (2) were mixed, and the decreasing and disappearingtime of the newly formed PL wavelength increased from about 60 times toabout 360 times compared to the reduction and disappearance times ofsubstances Formula (1) and (2), respectively. It is considered whenmixed with the compound of the present invention, not only electrons andholes are moved through the energy level of each substance, but also theefficiency and life span are increased by electron, hole transport orenergy transfer by a new region (exciplex) having a new energy levelformed due to mixing. As a result, when the mixture of the presentinvention is used, the mixed thin film is an important example showingexciplex energy transfer and light emitting process.

The reason why the combination of the present invention is superior toComparative Examples 8 to 9 in which a comparative compound is used as aphosphorescent host is that the high T1 and high LUMO energy valuesimprove the electron blocking ability and allow more holes to be movedto the emitting layer more quickly and easily when a compoundrepresented by Formula (1) having a strong hole property is mixed with apolycyclic compound represented by Formula (2), which is characterizednot only by electron but also by hole stability and high T1. As aresult, the charge balance in the emitting layer of holes and electronsis increased, so that light emission is well performed inside theemitting layer rather than at the interface of the hole transport layer,and therefore the deterioration in the HTL interface is also reduced,thereby maximizing the driving voltage, efficiency and life span of thedevice.

Among the compounds represented by Formula (1), it has been confirmedthat Dibenzofuran substituted compounds exhibits the best results interms of the driving voltage, the efficiency and the lifetime, andDibenzothiophen substituted compounds are also excellent in terms ofefficiency due to their high refractive index. That is, it is concludedthat the combination of Formula (1) and Formula (2) is electrochemicallysynergistic to improve the performance of the device as a whole.

As shown in Table 7, the mixture of the compound of the presentinvention was measured by fabricating the device in (2:8, 3:7, 4:6,5:5). To explain the results in detail, in the result of the mixture ofthe compound 1-33′ and 3-61, the results of the driving voltage, theefficiency and the life span were similarly excellent at 2:8 and 3:7,but as the ratio of the first host increases, such as 4:6 and 5:5, theresults of the driving voltage, the efficiency and the life span aregradually decreased, this was also the same in the result of the mixtureof the compound 1-50′ and 3-6. This can be explained by the fact thatthe charge balance in the emitting layer is maximized when anappropriate amount of the compound represented by Formula (1) havingstrong hole properties such as 2:8 and 3:7 is mixed.
